<h3>Peruvian adaptations to their physical environment</h3>
Explanation:
The Peruvians adapted to their natural environment of high altitude mountains like the Andes. The mountains created environmental challenges like low temperature, decreased precipitation, poor thin soil etc.
The Peruvians utilized the mountains in the most sustainable and efficient way both for agriculture as well as irrigation purposes. They followed terrace agriculture along the high mountain regions and built aqueducts to supply water for drinking and irrigation.
The agricultural terraces were constructed in such a way it received a good amount of sunlight even though sunlight was blocked by the surrounding high mountains. The crops were spaced widely to ensure proper sunlight and crop growth.
The irrigation system through aqueducts was constructed to prevent flooding.
